Find your USB stick in the output

Umm, how about:

Change .raw extension to .dmg

Mount image with Disk Utility -> Restore to Flash Drive.

It won't restore EFI partition and boot sectors (drive won't be bootable on hackintosh).

Am I only one who is having problems to make bootable usb? I write ''% diskutil list'' in terminal and it comes up as no such job.

Saudações!
Uma pergunta "estúpida": essa imagem raw é para PC Intel apenas ou serve para notebooks também?
Se sim, é só instalar as kexts necessárias para touchpad etc?
Obrigado.

Ela instala apenas o sistema original, sem modificações. Você precisa instalar as kexts necessárias para o seu hardware, independente de ser laptop ou desktop. As kexts e boot loader incluídas na imagem servem apenas para o boot do instalador e boot inicial do sistema através do pen drive.

Is there a way for me to be able to tell when the process is finished, will it prompt me in Terminal or do I just have to keep checking with Control+T until it stops?
